The largest crane system
constructed to date by J D Neuhaus
has been delivered to Westcon
Lofteteknikk AS (WCL) of Norway
for use on an offshore drilling rig.
The semi portal design comprises an A-frame supporting twin overhead horizontal track beams providing a 7.5m span.
The crane is approximately 11.5m high with a total weight of 32t. It is equipped with JDN hydraulic EH 40-H monorail hoists operating on each of the twin beams, each hoist providing an individual lift capacity of 40t. These hoists can be operated individually or simultaneously from one control and when used in conjunction, can lift 80t to a height of 12m. A JDN Profi 6 TI-H hoist with 6t lift capacity also covers other operational or service requirements.
